About the avoided emissions study

The study is the first to utilise WBCSD’s Avoided Emissions Guidance to study mining processes and the avoided emissions results have been independently assured by SLR Consulting Limited. Three of Weir’s technology combinations were evaluated against a conventional comminution circuit design for an archetypal mine processing 15 million tonnes of copper ore per year in Chile.

All three of the technology combinations are shown to yield sizeable benefits versus the traditional circuit. In the optimal combination, the comminution process consumes around 40% less energy and can avoid up to 50% of CO2e emissions. Importantly, there is no trade off elsewhere, as the redefined process uses less water too.
